有人可以帮助我找出代码中的错误吗?(Python 基本 GUI)

Question

我最近才开始接触python(只用java和JS编码(，并想尝试制作一个简单的数字键盘GUI。我仍然习惯于缩进格式。

我已经应用了正确的缩进并修复了所有拼写错误和语法错误，但仍然收到以下错误

"回溯(最近一次调用(： 文件"/home/pi/桌面/实验室工作/实验室 1/数字键盘测试 GUI.py"，第 4 行，在 类 BaseWindow(tkinter.Tk(： 文件"/home/pi/Desktop/Lab Work/Lab 1/Number Pad test GUI.py"，第 8 行，在 BaseWindow 中 self.minsize (x，y( 名称错误：未定义名称"自我">

Answer 1

你好像改变了你的问题。 尝试将 tkinter.tk 更改为tkinter。Tk与大T。

此错误表明您忘记在 lambda 函数之前放置逗号。

"line 60 self.bind("" lambda CatchEvent: self.CheckCode()) ^SyntaxError: invalid syntax"

您是否尝试过添加逗号？
检查第 5 行和第 110 行，您忘记了结束函数参数中 def 和冒号后面的空格。
也检查第 86 行，您在第 82 行将键定义为 Key，因此您必须在第 86.
检查第 88 行，它显示self.;after。请删除分号以避免语法错误。
您使用的文本编辑器是什么？如果使用 vscode，它将用红色下划线显示错误。

包括"self.minsize (x， y(;self.maxsize(x， y(" 在函数内 类中的任何语句都必须位于函数内 例如： import tkinter， tkinter.ttk as ttk 导入随机

类 BaseWindow(tkinter.Tk(： def _Change (自我(： x，y = self.winfo_width((， self.winfo_height(( self.minsize (x， y(;self.maxsize(x， y(
